Contourite and mixed turbidite-contourite systems in the Mozambique Channel (SW Indian Ocean): Link between geometry, sediment characteristics and modelled bottom currents

Sedimentary model for mixed depositional systems along the Pacific margin of the Antarctic Peninsula: Decoding the interplay of deep-water processes

“…A mixed system fluctuates across a continuum of transport, depositional and erosional processes, resulting in turbidite-dominated to contourite-dominated deposits. Therefore, we conclude that a mixed system comprises a wide variety of features and deposits formed under synchronous, asynchronous and passive interactions, as recently proposed by Rodrigues et al (2021) and Miramontes et al (2021). The term "hybrid systems" should be used when the interactions between the two processes are mostly synchronous in time and space (Rodrigues et al, 2021).…”

Incision of Submarine Channels Over Pockmark Trains in the South China Sea

“…The generation of channels transverse to continental slopes is mainly controlled by gravitational processes (de Leeuw et al., 2016; Fildani et al., 2013; Li et al., 2015) but can also be influenced by oceanographic processes such as dense shelf‐water cascading and internal waves (Puig et al., 2014). In contrast, contour currents are the primary control on the evolution of channels parallel to the slope bathymetry (García et al., 2009; Miramontes et al., 2020, 2021; Rebesco et al., 2014; Stow et al., 2013).…”

Upslope migrating sand waves on sediment-starved shelves: An example from the southeastern continental margin of the Korean Peninsula

“…Internal waves forming at the interface between water masses (e.g., Breitzke et al, 2017) is another possible cause for the formation of dunes (Reeder et al, 2011;Ribó et al, 2016;Zhang et al, 2019;Miramontes et al, 2020). However, internal waves generally develop on upper continental slopes where pycnoclines with higher density gradients can develop (Reeder et al, 2011, Ma et al, 2016Miramontes et al, 2021). This is dissimilar to the deeper marine setting of our study area, where the transition between water masses of distinct densities is yet to be documented.…”
